The present study examined the factors influencing the occurrence of flooding, risk and management strategies in Lagos, Nigeria. A set of questionnaires was administered to 400 respondents in four randomly selected settlements in Lagos State based on perception and observation methods. Descriptive and multivariate statistics and cartographic mapping techniques were employed for data analysis. The result indicates that the majority of the respondents live in a rented room and parlor. The significant flood risks include poor sanitation, a breeding site for mosquitoes, water contamination/waterborne diseases, and mental stress. Factors analysis explains 74.62% of the variance, indicating anthropogenic, natural, and institutional factors influencing flooding in the study area. The dominant flood management measures are clearance of drains, environmental sanitation, public awareness, training/education, while the significant steps taken by the government to ameliorate flooding challenges in the area include awareness, early warning, and education. The study concluded that there exists a significant difference in the factors influencing flooding across the settlements based on the ANOVA result given as: (DWSD F = 19.661, p < 0.05; RI = 41.104, p < 0.05; WIC = 18.123, p < 0.05; HWL = 37.481, p < 0.05; SD = 10.294, p < 0.05). The study contributes to knowledge using cartographic techniques to map the risks of flooding for easy understanding. The study has potential policy implications for planning and interventions in areas vulnerable areas. The study recommended monitoring of construction activities, enforcement of building codes, awareness campaigns, and early warning flood technology for sustainable flood management in the area.

Fourteen samples were collected from hand dug wells and boreholes, seven each from rural and urban land uses in the study area. Ten parameters (pH, electrical conductivity, total dissolved solids, total hardness, calcium, magnesium, chloride, nitrate and sulfate) were determined using standard methods. The resulting water quality indices revealed that 58.09% of the samples were rated very poor while 21.73%, 9.08% and 11.1% were rated poor, good and excellent, respectively in rural land use. The analysis of samples drawn from urban land use revealed that 76.55% of the water was unfit for drinking while 14.4%, 6.42% and 2.63% were found to be very poor, good and excellent, respectively. pH, total dissolved solids, chloride, total hardness and nitrate were beyond the permissible limits for urban land use while, pH, total hardness and nitrate were above permissible limits for rural land use. These parameters were fo...

Sample were analyzed for 7 heavy metals including Iron, Copper, Cadmium, Manganese, Lead, Zinc and Chromium using standard method.The results show that the concentration of heavy metals ranged between nd-55.18 mg L1. Zinc recorded the highest mean concentration of 18.12 mg L1 followed by Manganese (2.89 mg L1) while Chromium recorded the lowest mean value of 0.02mg L1 in the study area. The computed contaminated index ranged between 15.4-432.06.The highest contamination value was recorded at location G5 followed by G2 while location G9 recorded the lowest contamination value in the study area.It was concluded that contamination level is high.Cadmium accounted for about 23.3% for the contamination of groundwater quality deterioration while Lead and Copper accounts for 19.3 and 8.8% respectively.The study recommended treatment, proper maintenance and compliance to the specification of lanfill according to the world standard.

Samples collected were designated (OWS1-OWS5) representing 5 sampling points and were analyzed for 14 parameters including; (pH, TSS, TDS, Cl, EC, BOD, COD, DO, Pb, Cr, Cu, Hg, Fe and Zinc) during the month of September 2009. The mean value obtained for total suspended solid & zinc were above FEPA stipulated tolerance limit in OWS2& OWS5whereas for zinc, it was above the stipulated limit in OWS2, OWS3and OWS5. Cr was not detected except in two locations (i.e. OWS3& OWS5). Although there is no FEPA’s limit for EC, the concentration obtained in OWS2& OWS5were relatively higher than the mean obtained. Mercury and Lead were not detected in all the samples.

A total of 220 structured questionnaires were administered to studentsand staff across the institutions using a random sampling technique. Descriptive statistics and ANOVA wasemployed to analyse the data. The result shows that approximately 54% of the respondents are acquainted withthe WaSH program. The significant water supply sources include borehole and public piped borne waterrepresenting 86 and 13%, respectively. About 96, 94, 91 and 37% of the respondents gained access to wastebins, sanitation, water, and handwashing materials. The ANOVA shows a significant difference between thedependent variables across the institutions. At the same time, the post-hoc tests confirm a significant differencebetween YABATECH and the other two ...

The study examined inequalities in access to water and sanitation in rural settlements covering Apa, Ikoga, Ibeshe, Itori, Eruwa, and Lanlate in parts of Southwest Nigeria. Purposive and random sampling techniques were employed to select six settlements and administered 400 questionnaires to households respectively. Descriptive statistics, chi-square, and factor analysis were employed for data analysis. The result shows that the majority of the households interviewed are adults with secondary school certificate. The major available water supply and sanitation facilities in the study area are boreholes and an open pit latrine. About 50.8% and 48.1% of the households gained access to improved water and sanitation respectively in the study area. Badagry and Ewekoro recorded the highest access for improved water and sanitation respectively. Only 8% of the households gai...

This study examined patterns of household access to water supply in suburban settlements in parts of Lagos State,Nigeria.Data used for this study were obtained from social survey on access through questionnaire administration of randomly sampled 200 household members from four settlements each from Badagry and Ikorodu local government areas during the month of September 2012.The results showed that, boreholes, protected dug wells, vendors providing water, and rainwater harvesting were the main sources of water in the study area. Access to improved water source revealed that Igbogbo, a settlement from Ikorodu had the highest score with about 16.1%. About 21.7% of the households have access to safe water. A dependent relationship was established at p<.000 between the settlements and safe water sources. The pattern of access to improved water source showed that, households from Iworo-Ajido and Igbo...
